Overview

The NSI Polaris IPLDH750-3 Multi-Tap Dual-Sided Entry Connector is a heavy-duty, pre-insulated splicing solution engineered for secure, high-current connections in demanding industrial environments. This 3-port connector accommodates wire sizes from 750 MCM down to 1/0 AWG, making it ideal for high-amperage applications where reliable conductivity is critical. The aluminum alloy body is wrapped in high-dielectric strength plastisol insulation, providing both electrical protection and mechanical durability against abrasion, chemicals, and UV exposure. Each dual-sided port features two pressure screws for optimal conductor retention and includes removable access plugs for flexible cable entry from either side. Installation requires only a hex key and torque wrench—no additional tape or covers are needed, reducing labor time and material costs. The IPLDH750-3 is dual-rated for copper and aluminum cables, with maximum ampacity ratings of 535A for copper and 435A for aluminum. Rated for 600V and operating temperatures up to 90°C, this connector is designed for use in cable trays, panel boards, ducts, raceways, or troughs. The compact dimensions (4.95" L x 4.46" W x 3.30" H) and 550 in-lbs torque specification ensure compatibility with tight installation spaces while meeting rigorous performance standards. Whether for new installations or maintenance, the IPLDH750-3 delivers a time-saving, code-compliant alternative to traditional uninsulated connectors.
  • Dual-Sided Wire Entry: Form secure connections between 3 conductors quickly using the double-side entry ports sized for wires between 750 and 250 MCM
  • Heavy-Duty Performance: Wider and stronger connector blocks feature two pressure screws for each cable to ensure a secure connection in demanding applications
  • Ergonomic Design: Rounded corners and a smooth exterior finish over the abrasion-resistant plastisol insulation make Polaris connectors comfortable to grip
  • Removable Plugs: Each port and set screw comes with a secure plug to prevent debris from entering the insulated connector
  • Pre-filled Oxide Inhibitor: All 3 dual-sided entry (DSE) ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
